WARNING
The appliance shall be stored in a room without
continuously operating ignition sources (example: open
flames, an operating gas appliance or an operating electric
heater).
CAUTION
Appliance NOT accessible to the general public, install it in

Duct installation (see
"12.2.2 Guidelines when installing the
15])
WARNING
Do NOT install operating ignition sources (example: open
flames, an operating gas appliance or an operating electric
heater) in the duct work.
CAUTION
In case of installation WITHOUT the duct on inlet side,
make sure to install the air filter. For more information refer
to the option list of the indoor unit.
CAUTION
▪ Make sure the installation of the duct does NOT exceed
the setting range of the external static pressure for the
unit. Refer to the technical datasheet of your model for
the setting range.
▪ Make sure to install the canvas duct so vibrations are
NOT transmitted to the duct or ceiling. Use a sound-
absorbing material (insulation material) for the lining of
the duct and apply vibration insulation rubber to the
hanging bolts.
▪ When welding, make sure NOT to spatter onto the
drain pan or the air filter.
▪ If the metal duct passes through a metal lath, wire lath
or metal plate of the wooden structure, separate the
duct and wall electrically.
▪ Install the outlet grille in a position where the airflow will
not come into direct contact with people.
▪ Do NOT use booster fans in the duct. Use the function
to adjust the fan rate setting automatically (see
Refrigerant piping installation (see

17]. Only mechanical joints (e.g.
braze+flare connections) that are compliant with the latest
version of ISO14903 can be used.
CAUTION
Install the refrigerant piping or components in a position
where they are unlikely to be exposed to any substance
which may corrode components containing refrigerant,
unless the components are constructed of materials that
are inherently resistant to corrosion or are suitably
protected against corrosion.
Electrical installation (see
